IviDownconverter Get Band Crossing Info [BCI]
IviDownconverterBandCrossingInformation Capability Group
This VI returns the band crossing information for sweeps. Sweep timing is influenced by points in the sweep where frequency bands are crossed. This VI returns pairs of start/stop frequencies over which the sweep timing is constant. Sweep timing between different pairs of start/stop frequencies is variable. Thus, users may choose to use the IviDownconverter Wait Until Settled VI between sweeps across bands. The bands are returned in ascending order of frequency. Use the IviDownconverter Number of Bands [BCI] property to determine how many pairs of frequencies will be returned by this VI.

instrument handle The instrument handle that you obtain from the IviDownconverter Initialize or IviDownconverter Initialize With Options VI. The handle identifies a particular instrument session.
Default Value: None |
 |
buffer size (2048) Pass the number of elements in the start frequencies and stop frequencies arrays.
Default Value: 2048 |
 |
error in (no error) The error in cluster can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
 |
actual number of frequencies Indicates the number of frequency values returned in each frequency output array. |
 |
instrument handle out The instrument handle that you obtain from the IviDownconverter Initialize or IviDownconverter Initialize With Options VI. The handle identifies a particular instrument session.
Default Value: None |
 |
error out The error out cluster passes error or warning information out of a VI to be used by other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
 |
start frequencies A user-allocated buffer into which the start frequencies for each band are stored. Each value is paired with the corresponding element in the Stop Frequencies output array. The frequencies are returned in ascending order.
Units: Hertz |
|
stop frequencies A user-allocated buffer into which the stop frequencies for each band are stored. Each value is paired with the corresponding element in the Start Frequencies output array. The frequencies are returned in ascending order.
Units: Hertz |
